As it stands now, UC employees that use those sharing services are reimbursed if they involve UC business-related travel. But if the ban goes into effect, it would be the first time a government entity banned those services.

Lt. Gov. Gavin Newsom has condemned the move, saying the services save money and urging the university to not push back against these innovative services.

"A university that is focused on the future and committed to fostering new technology should not work against innovators and entrepreneurs," Newsom wrote in a letter to UC President Janet Napolitano.

A ban on these services could make sense, however. If a university staff member were in an accident in an Uber or Lyft car, it's not clear which entity would compensate them. The staffer could theoretically sue the university for liability. That's why UC is still looking for ways to overcome safety concerns.

Regulators from the UC system aren't the only ones that have some concerns regarding the safety of services like Uber and Lyft. Earlier this month, Uber's own drivers staged a protest outside of Uber's office in Santa Monica. They're upset that Uber's insurance policy only provides coverage for its drivers when there's a passenger in the car. They're also peeved with the rating system, since drivers that get consistently bad ratings are at risk of getting booted from the service.

“It is astonishing that the UC system, a state entity, has chosen to disregard that Transportation Network Companies (TNCs) have been permitted and declared as safe transit alternatives for thousands of Californians by the California Public Utilities Commission (CPUC)," Uber spokesperson Eva Behrend wrote in a statement to Business Insider. "The Commission's Safety & Enforcement Division made sure that every licensed TNC maintained insurance providing a minimum of $1 million per incident. Uber's technology platform has allowed California entrepreneurs and consumers greater flexibility, freedom, and choice. We have reached out to the UC Regents to educate them about our best-in-class insurance, commitment to safety and the fact that TNCs are state regulated and permitted.”

Business Insider has reached out to Lyft, and Airbnb. We'll update this story when we hear back.
